Buck, I was hoping someone could answer your first post, as I myself was curious, but didnt have the answer either.
As for that Legacy Fleece product from Cabelas--I looked that one up. Good price too. I think I may go with that over the Ullfrotte Merino thermal underwear that you had previously posted on. I have never been much of a guy who has had wool, however I know that fleece sure is comfy to me.
Keep posting Buck, you are bringing some good ideas/items that I miss while paging right on past them in the catalogs.
